Figure 3. Map of the HBA region on human chromosome 16 identifying Illumina chip features flanking and internal to the α -3.7kb deletion.

Figure 3.

Ensembl GRCh37 chromosome 16 HBA region; Illumina HumanOmni2.5-4 feature match; (red boxes are perfect match of probe with ref sequence; Black boxes are lesser matches; boxes on same row/level are from same probe); SNP name boxes have GRCh37 positions; Green boxes are six features within the deletion region while the three brown boxes are the SNPs immediately flanking the region. Non-highlighted labels are other blast hits. Yellow boxes show regions of breakpoints/crossovers for the three known types of -α 3.7kb deletion; Homology boxes X, Y and Z indicated as per Hess et al. 28.
